CNC Spindles: How to Make Them Last Longer?
CNC spindles are the driving force of every CNC machine. They are used to hold and rotate the cutting tool in CNC machines to ensure precision cutting and shaping of materials.
Any damage in the spindle can greatly impact the speed and quality of the job or even bring production to a standstill. Therefore, it’s essential to understand how to make CNC spindles last longer, ensuring they function optimally and avoid costly downtime.
7 Ways to Extend the Lifespan of CNC Machine Spindles
How can you prevent your CNC machine spindle from wear and tear and make it last longer?
Here are seven ways to keep your grinder spindle in good working condition and extend its lifespan.
Identify the Need for Repairs
Similar to our health, prevention is better than cure when it comes to CNC machine spindles. The CNC spindle is the heart of every CNC machine. You need to regularly check for any sign of damage and address it before the CNC machine fails. One good way to achieve this is by paying attention to your CNC machine’s sound.
If you notice a strange noise or difference in the tone of the vibration, then the machine needs to be checked. This should be done by an expert, who would first note the vibration readings and then see if a rebuilding will be necessary. Doing this will not only prevent downtime, it will also save you unnecessary costs should it become a more significant problem.
Another essential thing to monitor aside from the vibration level is the temperature. If your CNC machine is overheating, something is most definitely amiss, and it can result in a more significant problem if it is not addressed immediately.
To detect a difference in the temperature level, you must first have a record of the temperature of the spindle’s front and rear bearings for each application. Some common causes of spindle overheating are excessive speed, poor lubrication or unfiltered or poorly filtered spindle coolant.
Regularly Inspect the Surface Finish
If you notice size inconsistency, chatter or any other irregularities on your surface finish, a potential problem is looming. Check your spindle to find out what the issue is early on and take corrective action before it escalates.
Invest in Remanufacturing/Rebuilding
Rebuilding is distinct from repair. When your CNC spindle is repaired, damaged components are removed and repaired or replaced, as the case may be. In rebuilding, however, almost all the spindle components are replaced with upgraded ones, restoring it to a like-new condition.
Be careful, though, rebuilding your spindle is as important as the vendor handling it. Choose a rebuilding service that has the experience and technical know-how to do the job.
Perform Advanced Testing and Verification
Conducting advanced testing and verification for your CNC spindles can optimize their performance and lifespan. The spindles must be run-in at their designed operating speeds and monitored for vibration and temperature changes.
Detailed reports should also be created for verification by quality assurance technicians before leaving the testing facility.
Make Sure the Spindle Is Protected from Coolant
Protecting your spindle from the coolant is another way to extend its lifespan. Intense coolant spray can contaminate your spindle, and when this happens, it can remove grease or oil from the bearings. Direct the coolant towards the tool and ensure it does not come in contact with the spindle.
Prepare a Detailed Report on Failures
Lastly, keeping a detailed report of your spindle failure can help you identify patterns and take preventive measures. The report should be backed by pictures as a point of reference.
